Abstract
A liquid xylitol composition that is non-crystallizing at low temperatures comprising, at between about 65 and about 90 weight percent dry solids, xylitol, in an amount between about 65 and about 90 weight percent of the dry solids, and sorbitol, in an amount between about 10 and about 35 weight percent of the dry solids. This liquid xylitol composition is preferably non-crystallizing at between about 0° C. and about 10° C. A process for producing liquid xylitol compositions, comprising co-hydrogenating a sugar syrup mixture comprising a sugar syrup having a dextrose equivalence (DE) of between about 20 DE and about 99 DE, in an amount between about 5 and about 35 weight percent of the mixture, and xylose, in an amount between about 65 and about 95 weight percent of the mixture. This process may be used to produce liquid xylitol compositions that are non-crystallizing at low temperatures.
